Your Lord knows that you [Muhammad] sometimes keep vigil nearly two thirds of the night and sometimes half or one-third of it, and so does a party of those with you. Allah measures the night and the day. He knows that you cannot keep it all, so He relented toward you. Recite from the Qur’ān as much as is easy [for you]; He knows that among you there are sick people and others travelling the land in quest of Allah’s favor; and yet others fighting for His cause. So recite from it as much as is easy [for you]. Perform your prayers, pay the zakāt, and give Allah a generous loan. Whatever good you send ahead for yourselves you will find it with Allah, better and much greater in reward. And ask Allah to forgive you; Allah is Forgiving, Compassionate.
